FILTER-PRESS.

Be it known that I, CHARLES IV. MnRnILp, of Berkeley, Alameda county, State of California, have invented an Improvement in the Construction of Filter-Presses, of which the following is a description.

The present invention relates to an mprovement in devices for adjusting and sup- I porting the sluicing pipe through which the sluicing liquid is introduced into the containers of pressure filters, and particularly to a device for adjusting and maintaming the position of the sluicing pipe from the exterior of the press without taking the of the container which fits into the frame of the press between the filter plates in the ordinary manner; d is the horizontal feed channel located in the center at the top of the container through which the mixture and valuable components are introduced into the press; 66 are, the drainage channels on either side, either or both of which channels may be used for the introduction of 1i uids, vapors or ases to the spacev behind the filter cloths if esired. The bottom 2 of the container or frame 1,is caused to slope downward from its opposite side inward towardthe'center, with the object of facilitating the discharge ofthe pulp resultant from Specification of Letters Patent.

the sluicing. In order to support the sluiclng pipe 19 within the press, I provide at any suitable number of intermediate points 1n the length of the pipe, throughout the press, supporting blocks, preferably of wood, each of which, by means of screws 21, is ad ustable from the outside through the bottom of the press. The pipe 19 is fitted with the collars 22 to bear on said blocks, so that the wear incident to any rotary movement imparted to the pipe Will fall on the collars 22 and not on the pipe itself, and the latter Wlll consequently not become weakened, and will be always sufliciently supported to prevent the sagging which otherwise would occur and so afi'ect the uniformity of the sluicing action in the different containers throughout the length of the pipe.

It will be observed by an examination of Fig. 1 that the block 20 is arranged to slide upward in a slotted opening in the projection 9 on the bottom of the container, and by moving the screws 21, the block 20-can be raised and lowered in the seat, and the pipe 19 adjusted without taking the parts apart.

I claim as my invention:

The combination with the rotary sluicing I pipe of a verticalsupporting block passing through an opening in the frame of a container, and devices for adjusting the same from the exterior of the press, substantially as described In testimony, that I claim the foregoing as my invention, I have signed my name in presence of two witnesses, this twenty-first day of February, 1911.
